1 Supply Connection Plans of the PANDA Cluster- Jet Target, Beam Dump and its Interface with other Modules MEC session GSI Darmstadt Benjamin Hetz WWU Münster Institut für Kernphysik WWU Münster

2 Content of this talk Two main topics: PANDA target supply connections and later on spectrometer platform wiring Beam dump backing pump pipe ideas Target status information interface Benjamin Hetz WWU Münster 2017/12/14 2

3 Status of the PANDA WWU Münster Setup in very close to PANDA geometry with final Beam Dump Daily Cluster-Jet production and optimizations studies running Current activities: Investigation/optimization of vacuum conditions at interaction point distance Beam dump backflow rates Target density optimization using PANDA Prototype target Last electronic/software improvements for COSY in summer 2018 Benjamin Hetz WWU Münster 2017/12/14 3

4 Sketch of the needed electrical, gas supply, coolant, etc. of the PANDA cluster-jet target. 4

5 Components placed upon the target spectrometer platform Benjamin Hetz WWU Münster 2017/12/14 5

6 Antiproton Beamline 6

7 Components placed upon the beam dump platform 7

8 Our idea is to have two separate located distribution patch panels (provided by FAIR) offering us power, gas, coolant etc. with the desired connectors at each platform. 8

9 From the distribution patch panels the connection is made to the target devices, e.g. the CEE power connectors. 9

10 Target modules connected internally (cables and pipes bundled in cable ducts). 10

11 PANDA Hydrogen Gas/Purifier System can be located anywhere but somewhere near the solenoid. More details will come from the responsible Vienna group about sizes connections etc. Benjamin Hetz WWU Münster 2017/12/14 11

12 Location of the Cluster-Jet Target Rack We bring our own rack for the cluster-jet source Already completely filled and set into operation at Münster Concrete location and size already shown in the latest PANDA step files Connections, power lines, etc. shown in the previous slides Benjamin Hetz WWU Münster 2017/12/14 12

13 Location of the Beam Dump Rack The rack 42U-T1009 on platform TW East can be claimed (talked with Jost Luehning) So we d like to claim the whole rack for the beam dump electronics About 1/2 is filled with the turbopump supply units The other half can be used for the final BD slow control system by the Warsaw group No concrete plans how much space is needed, yet Benjamin Hetz WWU Münster 2017/12/14 13

14 Cable Duct Ø 40 mm 19" Rack CJ- Source MEC GSI A (very) rough sketch of the target/pumping station location View onto the target spectrometer platform Cable Duct Ø 160 mm Compressor Cluster-Jet Source Frame Cable Duct Ø 51 mm Pumping Station Indicated is the routing of our cable ducts for internal target communication only, these wires do not need communication with something else but our slow control system More or less to treat as one big cable External communication given by WAN connection point from the 19 rack (see prev. slides) Benjamin Hetz WWU Münster 2017/12/14 14

15 Backing Pumping Pipe Ø 70 mm MEC GSI A (very) rough sketch of the needed beam dump backing pump line Pumping Station Beam dump located beneath the detector Beam dump needs a backing pumping pipe to the pumping station at the target spectrometer platform Additionally a backup backing pump near the beam dump would be worthwhile No concrete plans do exist about pumping line routing, yet Beam Dump Benjamin Hetz WWU Münster 2017/12/14 15

16 Information for and from the other detector modules Which concrete target parameter are wished to be directly accessible by others? (cf. Excel Tables of PANDA controls requirements) Pressures? Valve states? etc How to supply this information? Hard wired? EPICS? We need: Information about target cross shutters (FZ Jülich), best hard wired Luminosity Monitor information E.g. some feedback loop for instant thickness adjustments Benjamin Hetz WWU Münster 2017/12/14 16

17 Summary Target supply connection and wiring wishes shown Concretization of backing pump system for beam dump needed Separate backing pump/long backing pipe/both? Which target status information should be shared in which manner? DSS/Interlock, etc. wishes? Benjamin Hetz WWU Münster 2017/12/14 17
